LATCH.

Specification of Letters Patent. Patented Mar. 23, 1920.

Application filedApril 10, 1919. Serial No. 289,036.

To all whom it may concern.-

Be it known that I, CHARLES S. BARNARD, a citizen of the United States, residing at the city of Bridgeport, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Latches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in cabinet locks, and the primary object thereof is to provide a lock of this type which is of simple and economical construction and which involves a minimum of parts, so as to permit of cheap construction and easy and quick assemblage.

A further object of the invention is to provide a lock which has an easy and quick as well as certain movement, so as to require slight effort in the operation thereof.

I11 the drawings:

Figure 1 is a front elevation;

Fig. 2 is a side elevation;

Fig. 3 is a rear elevation, and

Fig. 4: is a section taken on the linel4: of Fig. 3.

In proceeding in accordance with the present invention a casing 1, is employed which may be attached to the door by means of screws as shown, or by the use of the usual hollow interiorly threaded posts that are engaged by screws driven from the back of the door. A handle of somewhat bail construction 2, has pintles 3, and 4 which are passed through openings provided therefor in the sides of the casing so as to provide journaling means for the handle. An arm a, is carried by the handle so as to be eccentric to the journals thereof and engages the usual keeper 5, as depicted in Fig. 1, of the drawings. The pintle 4 carries a finger 6, on its inner end the finger extending at right angles to the pintle 4: and by engageinent with the front wall ofthe casing restricts outward movement of the handle. This finger also serves to engage one end of a coil spring 7, so as to hold the handle under tension, the spring being coiled about the pintle 4E, and having its opposite end abutting the front of the casing.

For the purpose of limiting the inward movement of the catch or handle, a lug 8,

is struck out from the side of the casing adjacent to the arm 4-. and is located so as to engage an inclined face 9, formed on the inner end of the handle as illustrated in Fig. 2, of the drawings.

The arm a forms a bolt or catch member which swings beneath and from beneath the keeper 5, due to the eccentricity of the bolt or catch member.

From the foregoing it will be apparent that the entire structure involves but three parts, namely, the handle or catch construction, the coil spring, and the casing, the handle and easing being each formed of a single piece of material, or integral throughout. The structure is accordingly not possessed of a multiplicity of parts likely to become disorganized and consequently render the device inoperative, and in addition the two positive stops prevent undue stresses being imposed upon the spring, so that the parts are not likely to become out of order.

What is claimed is:

1. In a latch of the type described, a wasing having openings in its sides and a lug struck-out from one side and disposed adj cent the opening in said side and projecting outwardly from said side, a handle having pintles engaged through the openings, and having an arm eccentric to the pintles, said handle having an inclined face on an inner end thereof between the arm and adjacent pintle to engage said' lug, a finger carried by one of the pintles and engageable with the front of the casing to limit outward movement of the handle, said lug and face upon engagement limiting inward movement of the handle, and a coil spring surrounding the last named pintle and having its ends engaged with the front of the easing and finger respectively.

2. I11 a latch of the type set forth, a casing having openings in its sides, a handle having pintles engaged through the openings, an eccentric arm carried by the handle to form a catch member, a finger carried by the pintle adjacent said arm to engage the front of the casing to limit outward movement of the handle, a stop member on the outer face of a side of the casing engageable with the handle to limit inward movement thereof, and a spring coiled about said pintle having the finger and engaged with the latter and with the front of the casing to hold the handle under tension.

7 3., In a latch, a casing, a stop extending borne by oneof the pintles and engageable with the front of the casing to limit movement 0]": the handlein one direction, an arm eccentric t0 the pintles and extending outwardly from a side of the handle anda part 011 the handle extending between said arm 10 and theadjacent pintle to engage the stop and to thereby limit movement of the handle in the opposite direction.

In testimony whereof I afiix my signature.
